4 way hoses are old news... built a permanent on-board air hose

[BAUS67]

I've seen that name on $300-400 kits. Seemed a bit excessive to me when I have about $50 into this and could have built it for about $100 if I hat to pay retail on everything.

Did you use plastic air lines to each corner, like a big rig???? or did you run steel/aluminum lines??? or rubber lines????

3/8 rubber with brass fittings and crimp bands.

I had something like this on my old TJ Rubicon almost 10 years ago. I plumbed/built it myself, had an air tank underneath the tub and a Viair compressor under the hood, with quick connects in the front and rear. Back then, I guess it was uncommon to see it and everyone that saw me using it, thought it was the coolest thing ever! I built a lot of custom stuff on that Jeep!

@Tricky Mike Would this system work on a Tundra? Asking for a friend (@604Bronco).

We don’t need to air down our tires…

… the Starbucks drive through’s are pretty well maintained…

But how's the Tim Horton's doing?

Strikes me as a fun project, but one more system that can break or somehow fail at some point in the future. Snag a line on some branch sticking out, can you mend the leak with Gorilla Tape and still air up your tires?

It strikes me as unnecessarily complicated. For starters, you have eight caps to remove, not four. Then four hose lines to connect, times two ends, meaning eight chuck connections. I admit that four 3-foot hoses is smaller and less weight.

I have the Thorslightning 300cfm 2-cylinder on a permanent install, plenty fast. My hoses are coiled up and stored in their round bag which is wedged between the right rear rollover strut and the right rear window, always with me.

Last, I can, and am happy to, air up anybody else with my two-way hoses.

But it sure looks cool!

I met the dude that came up with the system (or coined the name). It was definitely built on a budget lol. The final product was definitely way more refined and model specific but yeah you could totally diy it for cheap.

It's slower then my single bigger hose....

A bigger single hose should not do much for you. The Schrader valves are limited to ~2 CFM. At least on 33" tires a tiny Viair 88P goes from 20 to 38psi in 2:40 per tire and stores under the back seat. I have contemplated something beefier a number of times (most recently 2 weeks ago) but have never been able to talk myself into it. The next step up literally doubles the dimensions and shaves 15s per tire. Added a clip-on valve chuck to the 88P and called it a day.

And much slower than my single hose CO2 tank.

This is freaking sweet. I read some comments about fixing a problem that didn’t exist and I couldn’t disagree more. Pulling out a 4 way air hose sucks. Having air at each tire is freaking dope!!

That's fair. I started to use just a 2 way because I tired of dealing with hose tangles and bulk. Especially annoying when trying to limp along with a slow leak and frequent top ups. This mod would cost about $100 if you bought everything on amazon, less than buying a premade 4 way hose.

I made my own 2 tire hose kit that works with my 12v smittybilt compressor. Much cheaper compared to other options.
Pretty slick setup though! Now we need to figure out how to adapt onboard air jacks on our rigs, like the Le Man's cars.

It’s always been much less about how much hose you’ve got and much more about how you use it

 

[Squatch]

If I had steps, I would put the chucks at the ends of those. It might take some cutting, drilling. Old 80s-90s Jeep tubular steps would be easy, but all of this is a judgment call about work vs time saved/cool factor.

Always assumed I'd get the 4-way, but now I'm not sure I want to wrangle four hoses at once.

Great idea Tricky, I was wondering when someone was going to think of this.

Now all you need is 2 air jacks and you can use your air compressor to jack up the Bronc when you get a flat or to stack some rocks under it to get unstuck.

Fabricate some custom air jack/drop step/rock sliders and charge $5K per pair!
